As a child, I used to collect baseball cards. When my children were smaller, they started to collect Pokemon and Yu-Gi-Oh cards.

Rather than make apps for each type of card, we decided to create an app that can be customized for the type of card that is being collected. So it comes with some standard fields, but additional fields can be created as needed, the fields can be reordered, and even hidden if they are not needed. And a picture of the card can be captured with the camera or added from your photo library.
